The XL2 Lasergun (Laser Cannon in Serious Sam's Bogus Detour or simply Laser) is an experimental energy weapon that was created via reverse engineered energy weapons that are used by Mental's Bio-mechanoids.


The XL2 is still in early development, but initial field tests have been more than promising, hinting at a versatile weapon fit for many combat scenarios.

The XL2 has four barrels (two in Serious Sam's Bogus Detour) which fire in rapid succession, allowing the weapon to deliver a sustained barrage of “slowlight” laser pulses without running into danger of overheating. The body is entirely made of titanium which, in addition to being lightweight, further contributes to alleviating the common overheating problem that traditional laser weapons all too often face. Its revolutionary anti-recoil technology manages to completely eliminate the kickback caused by other slowlight launchers, making the XL2 precise and easy to use.

The lasers fired by the lasergun are projectiles, so it takes time for them to reach a target.

In Serious Sam 4, the lasergun behaves slightly different; continously firing the weapon will heat up the lasergun and increase its damage output, dealing twice as much damage as the projectiles did in the previous games. Its initial damage output is 50% higher than in previous game as well, dealing a base damage value of 30 per projectile and going to a maximum of 40.


The lasergun is a quite rare weapon, and often doesn't appear until the mid to late stages of the games it appears in.

Serious Sam 1[]

In Serious Sam: The First Encounter, the lasergun is first obtained in Dunes once the player enters the courtyard leading to the suburbs. In Serious Sam: The Second Encounter, the lasergun is obtained in The Pit in the Mayan era, the Courtyards of Gilgamesh in the Babylon era, and Land of the Damned in the Medieval era.

Serious Sam 3: BFE[]

It is worth noting that unlike previous games, the lasergun appears exclusively as a secret weapon, and not a regular weapon the player would normally find without secrets. It's because of this, its ammunition is also limited by how many secret electricity cells, or spare secret laserguns the player comes upon. On the other hand, if the player conserve its ammo and picks up all secrets that relate to it, they can reach its maximum ammo capacity part way through either Unearthing the Sun, The Guardian of Time, or Broken Wings (the latter only in Serious Sam Fusion as it has a new Fusion-exclusive secret containing 200 electricity, which will spawn an Adult Arachnoid once the ammo has been collected). In Jewel of the Nile, Sam first obtains the lasergun inside a Sirian chamber within the tomb of Isis in Gathering of the Gods. Unlike the main campaign, ammo for the lasergun is far more abundant in Jewel of the Nile and appears along with other types of ammunition.

Serious Sam's Bogus Detour[]

The lasergun is first acquired in Knee Deep in Sand, and then it appears for the second time in the later portions of the game.

Serious Sam Classics: Revolution[]

In the Bright Island campaign, the lasergun is first found in Forlorn Ruins, but can be found earlier as a secret in Crystal Cove.

Serious Sam 4[]

The lasergun, unlike its previous incarnation, is no longer found in secrets, though it is still quite a rare weapon. It is first obtained in In Carcassonne, and then for the final time in From Earth With Love.

Serious Sam: Siberian Mayhem[]

The XL2 does not officially appear in Serious Sam: Siberian Mayhem, having been replaced by the XPMR "Burner" Raygun. However, it is usable in the moddable version of the game and functions exactly the same as its Serious Sam 4 counterpart.

Your Laser Cannon projectiles will explode upon impact dealing splash damage in a small radius.

This upgrade enables the lasergun to fire an extremely powerful beam that can decimate enemies in its path, though at the cost of using up lots of ammunition.

This upgrade is obtained as the player progresses through the game.



  • The lasergun is a great alternative to the XM214-A Minigun, as it deals a similar amount of damage.
  • The lasergun is a great weapon for taking out hordes of Kleers. The beams fired by the weapon do great damage against a Kleer, and its rate of fire is fast enough to quickly do a lot of damage on a horde of them.
  • Because it takes time for the lasers to reach a target, the lasergun is not very effective against fast enemies at long range, such as Scythian Witch-Harpies. The player will very likely waste ammo trying to kill them while it would be far easier to switch to another weapon which would use less ammo to kill the same enemies.
  • Compared to the minigun, aiming should be done slightly upwards as otherwise lasers can hit hilltops, tops of ledges, or other objects/walls instead.
  • While the weapon fires quickly, it's still important to lead targets so as not to waste ammo due to the lasergun's projectile nature.

Serious Sam 1[]

  • It is also useful against slow or stationary enemies at any range, such as Fiendian Reptiloid Demons, Common and Highlander Aludran Reptiloids, Major Bio-mechanoids, and Zumb'uls. Slow enemies are very easy to predict, making it easy to land shots on them.
  • One or two lasers are enough to destroy a Fiendian Reptiloid Demon's fireballs in the HD releases.
  • The lasergun is best used when being attacked by a wide variety of enemies and rushing enemies have already approached to their attack range.

Serious Sam 3: BFE[]

  • Remember that in Serious Sam 3, both the weapon and its ammunition can only be found in secrets during the campaign, so it is recommended to use the weapon against tough enemies, confrontation of hordes of weak or medium enemies (such as Beheaded Rocketeers, Cloned Soldiers, or Juvenile Antaresian Spiders), or as a last resort.
  • The lasergun is useful against slow or stationary enemies at any range, such as Khnums, Major Bio-mechanoids, Technopolyps, Scrapjacks, and Adult Arachnoids. Slow enemies are very easy to predict, making it easy to land shots on them.
    • The lasergun does no damage to Khnums and Technopolyps in their boss fights in the original version of the game, so don't use it against them.

Serious Sam's Bogus Detour[]

  • The laser cannon is a strong weapon against large groups of Beheaded Kamikazes, Gnaars, Kleers, Minor Bio-mechanoids, Orc Captains, Orc Troopers and Sirian Werebulls, though it is best not to the use the weapon too frequently, as this will use up ammunition.
  • With the Overcharged Laser upgrade, the laser cannon is a much more efficient weapon against groups of small to medium-sized enemies, as the beams can eliminate them all quickly.

Serious Sam 4 / Serious Sam: Siberian Mayhem[]

  • Like in previous games, the lasergun is a very effective against hordes of beheaded enemies, Aludran Microhoppers, Gnaars, Kleers, Processed Anthropolyps, and Space Mummies.
  • Continously firing the lasergun allows the weapon to easily finish off large groups of enemies.
  • The death ray is extremely useful for destroying hordes of enemies, but firing it for too long will easily erase a lot of the weapon's ammo.
  • The death ray can easily destroy Saggitarian Sidewinders, although the player will have to keep their reticle on them at all times to destroy them quickly.

Behind the scenes[]

  • The lasergun did not appear in Test 1 or Test 2, but its ammo model could be found in both. In Test 2, the XL2 had a different texture, the ammo and sounds appeared in Test 2, and they were the same as in The Second Encounter.

  • The lasergun's firing sound in The First Encounter is different from the sound used from The Second Encounter to Serious Sam 3: BFE. In the classic version of The First Encounter, the lasergun sounds much like the laser cannons on a TIE Fighter from Star Wars. Subsequent re-releases of The First Encounter use the new firing sound introduced in The Second Encounter.
  • The lasergun's model in Serious Sam 3 was originally the one in Serious Sam HD.
